Interfacial Shapes in the Design of Composite Polymeric Materials

Renardy 9307238这个化学研究热学项目涉及在化学和热系统中分离两种不相容液体的界面形状。两种流体表现出完全出乎意料的现象，这是一种对一种流体流动的知识，并形成了一门丰富的跨学科科学。工业应用包括尼龙等双组分纤维的形成和照相胶片的生产。从理论上讲，分隔这两种流体的边界形状通常有多种可能性。此外，实验表明，某些形状比其他形状更受青睐，因此应研究选择机制，以缩小理论预测与实验结果之间的差距。在许多化学过程中，溶解添加剂和温度梯度的影响，以及界面上的热量和质量传递的考虑都是很重要的。提出者将使用物理模型、分析和计算技术来研究各种界面形状的稳定性，以及从不稳定排列到新排列的出现。复合材料的力学性能强烈依赖于界面形状。因此，了解组件性质对界面形状的影响具有重要的实际意义。***

Renardy 9307238 This chemical research thermal project concerns the shape of the interface separating two immiscible liquids in chemical and thermals systems. Two-fluid exhibit phenomena which are totally unexpected from a knowledge of one-fluid flows and form a subject rich in interdisciplinary science. Industrial applications include the formation of bicomponent fibers such as nylons and the production of photographic films. Theoretically, there are often many possibilities for the shape of the boundary separating the two fluids. In addition, experiments show that some shapes are preferred over others, so that the selection mechanisms should be investigated with the goal of lessening the gap between theoretical prediction and experimental results. The effect of dissolved additives and temperature gradients, and the consideration of heat and mass transfer at an interface are important in many chemical processes. Physical modeling, analytical and computational techniques will be used by the proposer to study the stability of various interface shapes, and the appearance of new arrangements from unstable ones. The mechanical properties of composite materials are strongly dependent on interface shapes. Thus, an understanding of the effects of the component properties on interface shape is of practical importance. ***
